<![CDATA[The purpose of this study was to analyze the effect of educational intervention on parents' knowledge and attitudes regarding complete basic immunization at Dolik Community Health Center. This study employed a quantitative approach with a pre-experimental one-group pretest-posttest design. A total of 16 parents participated as respondents. Data were collected using structured questionnaires to measure knowledge and attitudes before and after the educational intervention. Univariate analysis was used to describe respondent characteristics, while bivariate analysis was conducted using the Wilcoxon Signed Ranks Test. The results showed a substantial improvement in the proportion of respondents with good knowledge, increasing from 37.5% before the intervention to 75.0% after the intervention. Positive attitudes also increased significantly from 25.0% to 93.8% following the educational program. Statistical analysis demonstrated significant differences between pretest and posttest scores for both knowledge (p = 0.008) and attitudes (p = 0.001). These findings indicate that educational intervention is effective in improving parents' understanding and attitudes toward complete basic immunization. Strengthening structured health education programs at primary healthcare facilities may contribute to increased parental awareness, reduced vaccine hesitancy, and better adherence to childhood immunization schedules.]]>
